I had a good time at this airbnb. It's undoubtedly a great location, as it's only a ~3 minute walk from the Wat Mangkon MRT station. I was able to save a lot on transportation because of this. There are also a lot of great restaurants and food stalls available all day. (I'd recommend Lao Song Heng, a hole-in-the-restaurant in the street next to I'm Chinatown specializing in Dry Suki, it's excellent)
The shower pressure and the availablity of hot water is great. The air-conditioning unit was also really cold, which is a blessing considering the Bangkok heat and humidity. The dinnerware and utensils are minimal, but that's okay for a short stay, since you'll probably be eating out more often than not.
Advice in locating the airbnb if you're booking a Grab car: Tell the driver to enter through the driveway. It's after the drop off location of Asai hotel.
